The chromosomal locations of glutamate oxaloacetate transaminase gene loci in Japanese bunching onion (<i>Allium fistulosum</i> L., 2<i>n</i>=2X= 16, FF) and shallot (<i>A. cepa</i> L. Aggregatum group, 2<i>n</i>=2X = l6, AA) were investigated using alien monosomic addition lines (2<i>n</i>=2X+1=17, FF+nA, AA+nF) and hypoallotriploid lines (2<i>n</i>=3X-1=23, AFF-nA, AAF-nF) between these two species. The gene locus <i>Got-2</i> was located on the homoeologous sub-telocentric chromosomes, 6F in <i>A. fistulosum</i> and 6A in <i>A. cepa</i> Aggregatum group. The gene locus <i>Got-1</i> was on the other chromosomes. The present results indicate that chromosomal locations of these gene loci, at least <i>Got-2</i>, were conservative both in <i>A. fistulosum</i> and <i>A. cepa</i> Aggregatum group during speciation and subsequent evolution.<br>
